IMPROVEMENT IN LOOMS FOR WEAVING TERRY FABRICS.

Specification forming part of Letters Patent No. 211,815, dated January28, 1879; application filed April 10, 1878.

description thereof, which will enable others skilled in the art towhich they appertain to make and use the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to looms for weaving terry fabrics; and it consistsin the construction and arrangement of certain devices for weavinglooped or piled fabrics with any desired length of loops, as will behereinafter more fully set forth, and pointed out in the claim.

In the annexed drawings, to whichreference is made, and which fullyillustrate my invention, Figure l is a side elevation of part of a loomshowing my invention. Fig. 2 is a central vertical section of the samethrough the line a m, Fig. 4. Fig. 3 is a plan view of the breast-beamand lathe. Fig. 4 is a transverse vertical section through the line 3 3Fig. 1. Figs. 5, 6, and 7 are views showing the cams employed in theloom.

A represents the frame-work of the loom, with breast-beam B. G is thelathe, pivoted at its lower end in the usual manner to the frame, andoperated by pitmen D D from the crankshaft E. This shaftreceives itsmotion through gears M M from the driving-shaft L, and this latter shaftalso, by gears J J, communicates motion to a counter-shaft, I, uponwhich the cams, hereinafter described, are secured.

R is the roller on which the body-warp is placed, said body-warp passingupward over a roller, S, and then forward in the usual manner.

T is the roll for the terry warp, which is passed between two rollers, VV. IV is a ratchet-wheel 011 the journal of the lower roll, V, saidratchet-wheel being operated bya pawl, 2', on the arm Y. The arm Y isoperated by means of a rod or bar, Y lever Y and cam Z, which mechanismis so timed that the pawl will only operate on the ratchet-wheel at thetime when the devices hereinafter described take hold of and drawforward the terry warp to form the. loops.

On the breast-beam B are secured two slotted arms, A A, on which areplaced twosliding blocks, B B, which are connected by having the lowerjaw, 0 of a clamp secured to their inner ends. The upper jaw, 0?, ofthis clamp has its journals npassinginto the slides B. A link, m, issecured on the end of apin, m, in the outer side or end of each slide.

Each link on is pivoted to the upper end of a lever, D which lever ispivoted to a hanger under the breast-beam, and the lower end of the saidlever is, by a rod, D connected to a second lever, D pivoted at itslower end at the rear end of the loom.

The lever D isv provided with a stud and roller, p, working in a grooveon a cam, D secured on the shaft I. This arrangement of parts is for thepurpose of moving the clamp backward and forward at the proper time.

The length of the movement of the slides and the clamp between them maybe regulated by adjusting the connection between the levers D D and theextent of such movement regulates the length of the loop.

The upper jaw, 0 of the clamp has a slot ted arm, 0 through which passesa rod, 1 having pins 1) 10 through it above and below the arm.

The lower end of the rod I is attached to a lever, 1 which extendsrearward, and is pivoted in a stand, 1 at the back part of the loom.This lever I has a stud and roller, 8, which works in a groove on a cam,1 also secured on the shaft I, and causes the opening and closing of theclamp.

The warps pass between the jaws of the clamp, and the latter beingopened is moved inward toward the lathe at the proper time, and thenclosed upon the warp; and when it is moved outward toward thebreast-beam, it draws with it the portion of the warp which is .to formthe loops, it'having been let off by the positive motion of the let-offrolls, which are operated at the same timeby thedevices above Idescribed, the ground-warps being prevented from moving, so that theclamp and terry warps slide upon them aud form the loops, and after theloops are secured the clamp is again opened.

By this device loops of any desired length may he made in the fabric.

In this case I have only described the devices for forming the terrysurfaces and how the same are manipulated, it being understood that theshedding and take-up devices, though not shown, are to be substantiallythe same as ordinarily used in looms.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the arms A A, secured upon the breast-beam B. thesliding blocks B B, with the clamp O (J between them, and with links onm on their outer sides, the lever D, rod D lever D with roller 19, andthe cam D substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

7M. WEAVER.
